How to create a driver for Windows 7 x64 ?

Hello,

I would like to know the method to create some drivers for electronic cards
plugged on the PCI Express bus of computers.
I just begin in the programming world, I know the C++ language a little bit,
and I really need your help !

I will have to develop some drivers for a machine which is running with
Windows 7 Professional, 64 bits.
In my company, drivers for our electronic cards run well, but only for
Windows XP, 32 bits. We have never built these drivers with the new MS O.S.
or with a x64 machine.

I have the MS Visual Studio .NET 2003 and I use C++ to program. Here, for
these drivers, I will use this IDE to write the code and the WDK 7600.16385.1
to compile it. I have installed the WDK documentation too (with all
functions, samples etc.).

But, I don't know how to begin... I am not sure to use the good method and
material too... And, I have never built a driver before !
I am lost !
Please, is there someone to help me ?


Thank you so much!

Kind regards.
